That bluish compressor is what I use, you can borrow them from autozone for $10 or so. THey're a pain vs the baller aluminum donut/ring style, but the fixed aluminum style can only do 1 bore size per donut. Just be VERY careful, as it's very easy to break rings. Do not hesitate to re-compress them a few times if they don't slip right in.
So, got a new block/head on the way, will be taking the entire rotating assembly and slapping it into the new block after I get it bored/honed/surfaced.
Never installed pistons and paid the shop to do it the first time, but after somewhat completing a swap I feel a bit more confident that I could do it... Just need some opinions on what a good ring compressor consists of, and any other tips on installing them.
Would any of you reuse bearings/rings that ran in an engine for maybe 20 minutes total, that had oil/coolant mix?
Bearings may be iffy since they have a special coating for break-in on them. If the crank was micropolished and you were running loose clearances, they're probably fine.
I doubt your machine shop gave the block a plateau hone (medium grit for removal, then a quick fine grit to knock down ridges). The rings are probably still unseated if they didn't, therefore almost fresh, same for the bearings. If it was a low-power build I'd reuse it all. Otherwise I'd probably pop for some new shit.
